A 14.75 carat Ceylon moonstone — 16.21 ratti — at Rs. 9,380, about Rs. 636 per carat. This is the weight class men's silver rings are usually built around in Pakistan, substantial enough to fill a heavy shank without looking out of proportion.

Sizing a stone to a men's ring

The common mistake is buying too small. A men's silver ring with a broad shank needs real surface area or the stone reads as an afterthought, and a four or five carat cabochon simply disappears in that setting. Fourteen to seventeen carat is the range that works. Go much beyond that and the stone starts standing proud enough to catch on everything, which matters more for moonstone than it would for sapphire.

Silver, and why it suits this stone

Silver's cool grey is a natural partner for a pale translucent body and a blue sheen — the metal does not compete with the glow the way yellow gold can. It is also soft enough to work a close bezel around the girdle, which is exactly the protection a 6 to 6.5 Mohs stone with good cleavage wants. Ask your jeweller for a bezel rather than claws, and for a slightly recessed seat so the dome does not sit too high.

The sheen

Moonstone's glow is adularescence: light scattering between microscopically thin layers inside the feldspar, not pigment in the stone. It travels across the dome as the hand moves, which on a ring stone this size means the piece changes constantly through the day rather than sitting inert. Rock it slowly under a single lamp to judge it properly.

Rate, origin and care

At Rs. 636 per carat this sits in the lower middle of our range, which spans roughly Rs. 481 to Rs. 776 per carat. Recorded as a Ceylon stone. Clean it with warm water and mild soap only — no ultrasonic cleaner, no steam, no bleach — and take the ring off for anything rough. Treatment has not been tested, which we record rather than claiming the stone is untreated. Dimensions and clarity are not recorded yet; ask and we will measure.

This particular stone

This listing is one natural moonstone with a weight of 14.75 Carat. Its price is Rs. 9,380 — roughly Rs. 636 for each carat. Origin: Ceylon (Sri Lanka). Treatment: treatment not tested. Quote reference GS-000412 when you message us about it. The photographs show this exact stone, so what arrives at your door is the piece you chose on screen.

Above twelve carats you are into collector territory. Pieces this heavy are usually set as pendants or kept loose, and they are prized for the size of rough they came from. If you do set it, choose a bezel or a heavy claw to protect the edges.

On the Mohs scale moonstone rates 6 to 6.5. That is middle-of-the-road hardness: comfortable in pendants and earrings, and in rings worn with some care. Store it apart from harder stones so it does not pick up scratches, and wipe it with a damp cloth rather than scrubbing.

Whoever you buy moonstone from, make sure of three things: the stone is natural rather than lab-grown, glass or glass-filled; any treatment is stated in writing; and the weight quoted is the weight of the finished stone. We check every moonstone for those three points before it is listed, a certificate is available on request, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
